Abstract

1. Operating instrument with an ultrasonic drill probe (1) for shattering calculi in the human body, particularly hepatoliths and ureatoliths by means of ultrasonic energy, forceps (2-5) being associated with the tubular ultrasonic probe (1), characterised in that the tubular ultrasonic drill probe (1) is constructed as an actuator for the two outwardly springing legs (2, 3) of the forceps constructed as part of a leg spring, both legs (2, 3) by actuating an actuating device at the patient-remote end axially springloaded can be moved out of the patient-near end of the tubular ultrasonic probe (1).

Description

Die Erfindung bezieht sich auf ein Operationsinstrument mit einer Ultraschall-Bohrsonde zur Zertrümmerung von Steinen im menschlichen Körper, insbesondere Urether- und Gallensteinen, mittels Ultraschall-Energie, wobei der rohrförmigen Ultraschall-Bohrsonde eine Greifzange zugeordnet ist, sowie auch auf ein Operationsinstrument, insbesondere zum Fassen von Steinen, mit einer zwei Schenkel aufweisenden Greifzange, die axial gegenüber einem Führungsrohr bewegbar sind, wobei die Schenkel durch die Rohrmündung betätigt werden.The invention relates to a surgical instrument with an ultrasonic drilling probe for crushing stones in the human body, in particular urether and gallstones, by means of ultrasonic energy, the tubular ultrasonic drilling probe being assigned a gripper, and also to a surgical instrument, in particular for Gripping stones, with a pair of gripping pliers that can be moved axially relative to a guide tube, the legs being actuated by the tube mouth.

Es ist bereits ein gemäß Oberbegriff des Anspruchs 1 Operationsinstrument bekannt, bei dem die Greifzange als schnabelförmige Greifvorrichtung ausgebildet ist, bei der nur der eine der beiden Schenkel beweglich ausgebildet ist. Dadurch ergibt sich der Nachteil, daß nur ein kleiner Öffnungswinkel zwischen den beiden Schenkeln möglich ist (DE-OS-2 032 501). Bei einer weiteren dem Oberbegriff des Anspruchs 6 entsprechenden, Ausführungsform ergibt sich der gleiche Nachteil dadurch, daß die krallenförmigen Greifenden in der Art einer Pinzette ausgebildet sind und daher nur einen kleinen Öffnungswinkel zwischen sich haben. Um die erforderliche Weite der Greiferenden zu erreichen, müssen diese weit auseinander gefahren werden, was besonders im Harnleiter gefährlich ist. Außerdem wird dadurch die seitliche Stabilität vermindert (DE-OS-2 053 982, EP-A-0 065 054).A surgical instrument according to the preamble of claim 1 is already known, in which the gripping pliers are designed as beak-shaped gripping devices in which only one of the two legs is designed to be movable. This results in the disadvantage that only a small opening angle between the two legs is possible (DE-OS-2 032 501). In a further embodiment corresponding to the preamble of claim 6, the same disadvantage results from the fact that the claw-shaped gripping ends are designed in the manner of tweezers and therefore have only a small opening angle between them. To reach the required width of the gripper ends, they have to be moved far apart, which is particularly dangerous in the ureter. This also reduces lateral stability (DE-OS-2 053 982, EP-A-0 065 054).

Bei einem weiteren Operationsinstrument dieser allgemeinen Art allerdings ohne eine Greifzange ist ein Hohlraum zum Durchgang der Spülflüssigkeit dadurch freigelassen, daß der Draht der Schwingungssonde profiliert ist, derart, daß er selbst gegenüber dem außenliegenden Sondenkanal Hohlräume frei läßt (DE-PS-2 349 120). Dadurch wird eine hohe Flexibilität mit großer Kapazität verbunden, so daß insbesondere die Zertrümmerung von Urether- und Gallensteinen unter Absaugung der abgelösten Stein-Fragmente durch den Sondenkanal möglich ist.In a further surgical instrument of this general type, however, without a gripper, a cavity for the passage of the rinsing liquid is left free in that the wire of the vibration probe is profiled in such a way that it even leaves cavities free with respect to the external probe channel (DE-PS-2 349 120) . This combines a high flexibility with a large capacity, so that in particular the destruction of urether and gall stones with suction of the detached stone fragments through the probe channel is possible.

Ferner ist bekannt, Cystoskope mit in die Blase einzuführenden Lithotriptoren bzw. deren Elektroden in Verbindung zu bringen (CH-PS-470 172, US-PS-2 227 727).It is also known to connect cystoscopes to lithotriptors or their electrodes to be inserted into the bladder (CH-PS-470 172, US-PS-2 227 727).

Der Erfindung liegt die Aufgabe zugrunde, die Operationsinstrumente der eingangs erwähnten Art so zu verbessern, daß auch größere Steine auf kurze Distanz erfaßt werden können.The invention has for its object to improve the surgical instruments of the type mentioned so that larger stones can be detected at a short distance.

Zur Lösung dieser Aufgabe sind die kennzeichnenden Merkmale der unabhängigen Ansprüche 1, bzw. 6 vorgesehen.To achieve this object, the characterizing features of independent claims 1 and 6 are provided.

Auf diese Weise wird die Aufgabe gelöst, weil sich unmittelbar am Ende der rohrförmigen Ultraschall-Bohrsonde die Schenkel der Feder weit öffnen.In this way, the task is solved because immediately at the end of the tubular ultrasonic drilling probe, the legs of the spring open wide.

Durch die kennzeichnenden Merkmale des Anspruchs 2 wird außerdem eine seitliche Führung der beiden Federschenkel erreicht.Due to the characterizing features of claim 2, lateral guidance of the two spring legs is also achieved.

Weitere Vorteile und Einzelheiten der Erfindung ergeben sich aus der nun folgenden Beschreibung eines Ausführungsbeispiels unter Hinweis auf die Zeichnung. In dieser zeigen :

  • Figur 1 eine Seitenansicht auf das gesamte Instrument in verkürzter Darstellung ;
  • Figur 2 eine Seitenansicht auf das distale Ende mit stark ausgefahrener Greifzange in stark vergrößerndem Maßstab ;
  • Figur 3 eine um 90° gedrehte Seitenansicht auf die Ausführungsform nach Fig. 2 und
  • Figur 4 eine Seitenansicht wie Fig. 2, bei der sich jedoch die Greifzange in einer anderen Lage befindet.
Further advantages and details of the invention result from the following description of an embodiment with reference to the drawing. In this show:
  • Figure 1 is a side view of the entire instrument in a shortened view;
  • FIG. 2 shows a side view of the distal end with the gripping pliers extended to a greatly enlarged scale;
  • 3 shows a side view rotated by 90 ° of the embodiment according to FIGS. 2 and
  • Figure 4 is a side view like Fig. 2, but with the gripping pliers in a different position.

In Fig. 1 ist links das proximale und rechts das distale Ende des Operationsinstrumentes dargestellt, wobei es sich um ein medizinisches Greifinstrument handelt, das in der Regel in den Kanal eines Endoskopes eingeführt wird.In Fig. 1, the proximal end of the surgical instrument is shown on the left and the distal end on the right, which is a medical gripping instrument which is usually inserted into the channel of an endoscope.

Links sieht man zwei Rändelschrauben 10, 11, die gegeneinander geschraubt sind, und zwischen sich eine nicht dargestellte Spannzange beaufschlagen, die zur Befestigung der beiden Adern 6 und 7 dient. Weiter rechts sieht man einen Spülkanal 13, der in den Kanal für die Adern 6 und 7 mündet. Darunter ist die elektrische Leitung 14 sichtbar, die in den Schwingungskopf 15 zur Erzeugung der Ultraschall-Energie führt. Es handelt sich um einen Ultraschall-Wandler bekannter Bauart, so daß dieser nicht im einzelnen beschrieben werden muß. Daran schließt sich weiter rechts schließlich die Ultraschall-Bohrsonde 1 an. Im Innern dieser Ultraschall-Bohrsonde 1 ist der aus den beiden Adern 6 und 7 bestehende Draht der Greifzange angeordnet. In der dargestellten Lage sieht man auch, daß die beiden Schenkel 2 und 3 der Greifzange nach rechts ausgefahren sind, wobei sich ein sehr großer Öffnungswinkel zwischen den beiden krallenförmigen Schenkeln 2, 3 ergibt.On the left you can see two knurled screws 10, 11, which are screwed against each other, and act between them a collet, not shown, which serves to fasten the two wires 6 and 7. Further to the right you can see a rinsing channel 13 which opens into the channel for the wires 6 and 7. Below this, the electrical line 14 is visible, which leads into the vibration head 15 for generating the ultrasound energy. It is an ultrasonic transducer of a known type, so that it does not have to be described in detail. This is followed by the ultrasound drilling probe 1 further to the right. The wire of the gripping pliers consisting of the two wires 6 and 7 is arranged inside this ultrasonic drilling probe 1. In the position shown you can also see that the two legs 2 and 3 of the gripping pliers are extended to the right, with a very large opening angle between the two claw-shaped legs 2, 3.

Diese Lage der Greifzange ist dadurch entstanden, daß auf die äußere linke Rändelschraube 10 ein Druck nach rechts ausgeübt wurde. Wenn der Druck nachläßt, federt die Rändelschraube 10 nach links zurück, und die beiden Schenkel 2, 3 werden in die Ultraschall-Bohrsonde 1 zurückgezogen.This position of the gripping pliers resulted from the fact that a pressure was exerted to the right on the outer left thumbscrew 10. When the pressure subsides, the knurled screw 10 springs back to the left, and the two legs 2, 3 are pulled back into the ultrasonic drilling probe 1.

Die Einzelheiten sind in den Fig. 2-4 dargestellt, die nur das erwähnte distale Ende der Ultraschall- Bohrsonde 1 zeigt. Die Sonde ist in der Regel sehr lang, sie ist in Fig. 1 stark verkürzt dargestellt.The details are shown in FIGS. 2-4, which shows only the distal end of the ultrasonic drilling probe 1 mentioned. The probe is usually very long, it is shown in a very shortened form in FIG. 1.

In Fig. 2 sieht man die Adern 6 und 7 mit der sich oben daran anschließenden Greifzange. Diese Adern können zum Beispiel einen Durchmesser von nur 0,5 mm haben. Sie sind um den Niet 5 gewickelt, so daß dort eine räumlich gewundene Biegefeder 4 entsteht, in die die beiden Schenkel 2 und 3 einstückig übergehen.2 shows the wires 6 and 7 with the gripping pliers adjoining them at the top. For example, these wires can have a diameter of only 0.5 mm. They are wound around the rivet 5, so that there is a spatially wound spiral spring 4, into which the two legs 2 and 3 merge in one piece.

Es können die beiden Adern 6 und 7 auch aus einem durchgehenden Stück Draht bestehen, dessen Enden als Biegefeder 4 gestaltet sind und ein Niet die Enden Seite an Seite zusammen hält.The two wires 6 and 7 can also consist of a continuous piece of wire, the ends of which are designed as spiral springs 4 and a rivet holds the ends together side by side.

In den Fig. 2 und 3 ist die Zange sehr weit ausgefahren, um die Bauart sichtbar zu machen.2 and 3, the pliers are extended very far to make the design visible.

Fig. 3 zeigt das Gleiche um 90° verdreht. Hierdurch wird nunmehr auch der eine Schlitz 8 sichtbar, in dem der rechte Schenkel nach Fig. 2 Aufnahme findet. Demgegenüber ist noch ein weiterer Schlitz 9 für den anderen Schenkel 2 vorgesehen.Fig. 3 shows the same twisted by 90 °. As a result, the one slot 8 is now also visible, in which the right leg according to FIG. 2 is accommodated. In contrast, another slot 9 is provided for the other leg 2.

Fig. 4 zeigt die gleiche Seitenansicht wie Fig. 2, jedoch befinden sich hier die beiden Schenkel 2 und 3 in ihrer Arbeitsstellung in den Schlitzen 8 und 9. Während der Arbeit werden nämlich die Schenkel 2, 3 niemals so weit ausgefahren wie in den Fig. 2 und 3 dargestellt ist. Sie verbleiben vielmehr ständig in den Führungsschlitzen 8, 9. Auf diese Weise wird der nicht dargestellte gefaßte Stein durch die Federwirkung der Schenkel 2, 3 an die Stirnseite 16 der rohrförmigen Ultraschall-Bohrsonde 1 herangezogen. Ferner besteht die Möglichkeit, auf kurze Distanz größere Steine zu fassen. Wenn die Steine kleiner sind, wird die Greifzange noch ein wenig weiter in den Hohlraum hineingezogen, wodurch der Abstand der beiden Schenkel 2, 3 verkleinert und dem kleineren Stein somit angepaßt wird. Gleichzeitig wird der Abstand zwischen den Schenkeln 2, 3 und der Stirnseite 16 noch kleiner, was bei einem kleineren Stein auch erwünscht ist. Durch die Führung in den Schlitzen 8, 9 wird auch eine seitliche Stabilität der Schenkel erreicht. Aus diesem Grunde zeigt diese Ausführungsform den weiteren Vorteil, daß die Greifzange auch noch für andere Zwecke Verwendung finden kann. Tatsächlich wird der Stein durch drei Punkte stabil eingespannt, nämlich die beiden Schenkel 2, 3 und die Stirnseite 16. Bekanntermaßen ist die Dreipunktlagerung wesentlich sicherer als die Halterung zwischen nur zwei Punkten.Fig. 4 shows the same side view as Fig. 2, but here the two legs 2 and 3 are in their working position in the slots 8 and 9. This is because the legs 2, 3 are never extended as far as in Figs 2 and 3 is shown. Rather, they remain constantly in the guide slots 8, 9. In this way, the grasped stone, not shown, is pulled by the spring action of the legs 2, 3 to the end face 16 of the tubular ultrasonic drilling probe 1. There is also the possibility of grasping larger stones at a short distance. If the stones are smaller, the gripper is pulled a little further into the cavity, whereby the distance between the two legs 2, 3 is reduced and thus adapted to the smaller stone. At the same time, the distance between the legs 2, 3 and the end face 16 becomes even smaller, which is also desirable in the case of a smaller stone. Lateral stability of the legs is also achieved by the guidance in the slots 8, 9. For this reason, this embodiment shows the further advantage that the gripping pliers can also be used for other purposes. In fact, the stone is clamped stably by three points, namely the two legs 2, 3 and the end face 16. As is known, the three-point bearing is much safer than the holder between only two points.

Wenn der Erfindungsgegenstand als reine Greifzange verwendet wird, kann die Führung durch die Längsbohrung des Ultraschallwandlers 15 gemäß Fig. 1 ganz entfallen. Hierzu kann auch das Betätigungsstück 1 für die Greifzange lösbar mit dem Ultraschallwandler 15 verbunden sein. Dazu besteht die Betätigungshülse 1 aus einem dünnen langen Rohr, das mit einer Schraube 17 versehen ist, siehe Fig. 1, die in den Ultraschall- wandler einschraubbar ist.If the subject of the invention is used as a pure gripping pliers, the guidance through the longitudinal bore of the ultrasonic transducer 15 according to FIG. 1 can be omitted entirely. For this purpose, the actuating piece 1 for the gripping pliers can also be detachably connected to the ultrasonic transducer 15. For this purpose, the actuating sleeve 1 consists of a thin, long tube, which is provided with a screw 17, see FIG. 1, which can be screwed into the ultrasonic transducer.

Wenn der Erfindungsgegenstand mit einer Ultraschallbohrsonde verwendet wird, werden die .Adern oder Drähte 6, 7 nicht an den Ultraschall- wandler 15 angeschlossen. Es handelt sich also auch in diesem Falle bei der Greifzange um ein reines Greifinstrument, welches aber in der erwähnten überraschenden Weise dazu dient, die Wirksamkeit der Ultraschallbohrsonde 1 zu erhöhen.If the subject matter of the invention is used with an ultrasonic drilling probe, the wires or wires 6, 7 are not connected to the ultrasonic transducer 15. In this case, too, the gripping tongs are a pure gripping instrument, which, however, serves in the surprising manner mentioned to increase the effectiveness of the ultrasonic drilling probe 1.
